With respect, there's no need for conspiracy theories. It doesn't matter what CBU3 is or isn't doing behind the scenes; all that matters is the product you're paying for and whether you're satisfied with it. Regardless of whether CBU3 has been putting 100% or 1% of their effort towards FF14, it won't change the reality that the updates they've provided are the updates they've provided.

If you are satisfied with the product, sounds like a good reason to keep playing. If you're not satisfied with the product, sounds like a good reason to try something else instead. It's as simple as that.
